Could be a Cal 1342 ?
Well if it is, the watch is a lot earlier than 1989, they stopped fitting that around 1980. It more likely has an ETA movement IMO.
I think it is a pretty run of the mill piece, nice enough in isolation but not one to excite the collectors here. Much of the value is in the gold assuming it is solid and not plated. If plated then there isn't much value at all unfortunately.
